It was a messy job, but if you tape/drape/cover the interior really well, most of the aluminum shavings don't remain in the aircraft...although I'm still removing them from my hair a year later!
BTW, by the looks of your picture, Dynon changed the printing on the front of these panels (don't see the Dynon logo any longer). Minor change, but maybe more was done. You are going to love them Tony.
